HENRY RICE, OF BROOKLYN, NEW YORK.

BlLLlARD-TABLE LEVELER.

SPECIFICATION forming part of Letters Patent No. 372,566, dated November1, 1887.

Application filed April 14, 1887.

To aZZ whom it may concern:

Be it known that I, HENRY B1013, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented a certain new and useful Billiard-Table Leveler, of which thefollowing is a specification.

My invention relates to means designed to keep billiard-tables level andto easily and quickly compensate for any inequalities in the surfaceupon which the legs of such tables are intended to rest.

The importance of having astrictly level surface for supportingbilliard-tables is of course apparent, and in order to attain such aresult platforms are oftentimes erected specially to support the tables;but even when this precaution is taken shrinkage in the material ofwhich the platform is made, or in the foundation of the platform, or forcauses oftentimes impossible to account for, inequalities will manifestthemselves which render it necessary to provide some means whereby thelegs of the table may be adjusted to compensate for such defects.

My invention consists of a device intended to overcome theabovementioned difficulties, and it is hereinafter particularlydescribed, and its features of novelty pointed out in the claimsconcluding this specification.

In the accompanying drawings, in which like features are indicated bylike letters of reference in the several views, Figure 1 represents atop plan view of one embodiment of my invention, the two parts of thestructure being considerably separated. Fig. 2 is a side view of Fig. 1.Fig. 3 is a central longitudinal section through the line :0 w of Fig.1, the parts being shown drawn together. Fig. 4 is a top plan view ofthe lower member of my device. Fig. 5 is a bottom plan view of the topmember of said device; and Fig. 6 is a View similar to Fig. 3, showingaslight modification of the adjusting means.

Referring to the drawings, A indicates the bottom member of my device,and B the top member, these two parts being in the form of wedges, asclearly shown in the drawings, and are adapted to slide upon each otherin such manner that as they are drawn together the top member isgradually elevated. The bottom member, A, is provided with a groove, a,

to receive the adjusting-screw 1), whose head 0 projects at the end ofthe wedge, in order that it may be within easy reach, and is fitted witha collar, (1, which, in connection with the collar e, fixed upon theshank of the screw and operating in a groove in the block A, preventsthe screw from being withdrawn in either direction from said block.

0 indicates a guide-strip formed upon or secured to the upper surface ofblock A, which cooperates with the groove D in the under surface ofblock B, thereby preventing the blocks from moving laterally upon eachother.

E indicates a groove formed in block B, which is adapted to receive thescrew 1), as shown. At the end of groove E there is let into the blockthe nut f, which cooperates with the threads of the screw Z) in anobvious manner, whereby when the two members of the structure are placedtogether and the head 0 of said screw 1) is turned in the properdirection the gradual adjustment of the wedgeshaped blocks upon eachother is effected.

In the form of structure above described I propose to construct thewedge-shaped blocks of suitable metal as, for instance, castiron, steel,or brass; butin the modified structure shown in Fig. 6 of the drawingsthe said blocks may advantageously be made of suitable wood. In Fig. (5it will be observed that the grooves to receive the screw and theguidestrip and its cooperating groove are the same as in the other viewsof the drawings; but the headed screw, instead of being fixedly thoughloosely secured in the block A, merely passes through the end of theblock A and through an opening at the end of groove E of block B, and isprovided upon its end with an adj usting-nut, whereby the blocks aredrawn upon one another, as in the other construction. It is of course tobe understood that the blocks A and B may be made of variousthicknesses.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A device for adjusting billiard -tables, whereby their beds may bemaintained in ac curately -1evcl planes, consisting of wedgeshaped blockA, provided upon its inclined surface with a groove, a, and wedge-shapedblock B, provided upon its inclined surface with groove E, and with nutf, let into said block at the end of groove E, as shown, and Signed atNew York, in the county of New screw 6, cooperating with grooves a and EYork and State of New York, this 4th day of and with nut f,substantially as set forth.
